Check what Windows detects
Connect the intended display arrangement and open Windows display settings. Microsoft documents an Identify option that shows which number belongs to each detected screen and a Detect action for an expected display that is absent. Begin there instead of assuming that an application has failed because its window remains on the laptop. A detected second screen and a visible player window are different observations.
Choose the intended projection mode
Windows provides PC-only, duplicated, extended and second-screen-only choices through its projection controls. Duplicate shows the same desktop on both displays; Extend creates additional desktop space. Select according to the actual task rather than treating one mode as universally correct. If the television shows an empty desktop in Extend mode, move the relevant application window there before concluding that playback is absent.
Arrange the screens deliberately
Microsoft’s display guidance explains arranging detected screens to match their physical positions. Test the pointer movement between them after applying the arrangement. This can make it easier to move a player window to the television without searching beyond an unexpected screen edge. Keep the computer controls accessible until the intended layout works, especially before using a mode that hides the laptop display.
Test video and sound separately
Once the player is on the expected screen, use a short authorised sample and check audio output as a separate step. A correct display layout does not establish that the television is the selected sound destination or that a source supports every output arrangement. Record the connection, projection mode and exact symptom. This gives support useful evidence without changing a working account merely to move a window.
Questions, answered
Does an empty extended desktop mean the player has stopped?
Not necessarily. Extend creates separate desktop space. Confirm which screen holds the application window before treating an empty television desktop as an account or playback failure.
